Description
Technical Field
The embodiment of the invention relates to the technical field of train over-line operation control, in particular to a trackside equipment simulation method and system of interconnection and intercommunication over-line.
Background
In an indoor test platform, a trackside simulator is mainly responsible for simulating driving, collecting and displaying of real trackside equipment (such as a shaft counting section, a signal machine, a turnout, a shielded gate, an emergency stop button and the like) of a line, and completing equipment relay state collection and interlocking command response required by interlocking. Meanwhile, the trackside simulator also completes the simulation sending of the message information of the transponder, and completes the receiving of the message of the transponder by the vehicle-mounted equipment. In a common CBTC circuit, a trackside simulator mainly completes driving acquisition of trackside equipment of the circuit and message sending of a responder, and the trackside simulators of different circuits are not communicated with each other.
The interconnection and intercommunication of urban rail transit is to enable different vehicle-mounted devices to realize cross-line/collinear operation. However, the conventional CBTC line trackside simulator has the following disadvantages for processing the cross-line scene:
(1) in the scene that the train crosses the local line: a, at a cross-line demarcation point, two transponders of a target line are arranged in the line, but the transponders are controlled by the target line CI, and the line-side simulator cannot communicate with the target line CI and the LEU, so that message information corresponding to the transponders cannot be acquired, and a train is prevented from crossing into the target line. And b, the indoor vehicle dynamics model and the vehicle-mounted vehicle can only communicate with one trackside simulator at the same time, and when the trackside simulator calculates the occupation pressure of the axle counting section according to the position sent by the vehicle dynamics model, the trackside simulator cannot report the occupation of the train to the target line CI when the head of the train presses the tail of the line demarcation point and does not cross the demarcation point, so that errors occur in calculation of the CI and the ZC.
(2) In the scene of train crossing into the local line: a, at a cross-line demarcation point, two transponders of the line are arranged in the target line, but the transponders are controlled by the line CI, and the target line rail side simulator cannot communicate with the line CI and the LEU, so that message information corresponding to the transponders cannot be acquired, and trains are prevented from crossing into the line. And b, the indoor vehicle dynamics model and the vehicle-mounted vehicle can only communicate with one trackside simulator at the same time, and when the trackside simulator calculates the occupation pressure of the axle counting section according to the position sent by the vehicle dynamics model, the trackside simulator cannot report the occupation of the train to the line CI when the head of the train presses the tail of the line demarcation point and does not cross the demarcation point, so that errors occur in calculation of the CI and the ZC.
In the actual use process, the inventor finds that in the existing process of simulating train line-crossing operation, a train cannot acquire the line condition of a target line before the train completely enters the target line from the line-crossing, and the safety of the train entering the target line from the line-crossing cannot be guaranteed.
On the other hand, before the train completely enters the target line, the trackside simulator of the target line cannot acquire the occupation information of the axle counting section in the line in the cross-line area, and the delayed update of the occupation information of the axle counting section brings hidden troubles to the driving safety.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to enable a train to perform an overline operation (for example, a train traveling on No. 1 line travels into No. 2 line through an overline area, and travels on No. 2 line), an overline area is provided between different lines. Fig. 1 shows a schematic diagram of a track line for implementing cross-line operation according to this embodiment, referring to fig. 1, three different lines are line 101, line 102 and line 103, respectively, a cross-line area 104 is provided between line 101 and line 102, and a train can enter line 102 from line 101 or enter line 101 from line 102 through cross-line area 104. Similarly, a crossover region is also provided between the line 103 and the line 102, and a train can enter the line 102 from the line 103 or enter the line 103 from the line 102 through the crossover region. The station is denoted by 105 in fig. 1.
A demarcation point is typically located on the crossline area 104, such as where the dashed line meets line 104 in fig. 1, and is the demarcation point between line 101 and line 102. For example, in fig. 1, a line connected to the line 101 above the boundary point in the crossover region belongs to the line 101, and a line connected to the line 102 below the boundary point in the crossover region belongs to the line 102. Although which section of the line of the jumper area belongs to the line 101 and which section belongs to the line 102 is divided by the dividing point, since the jumper area substantially belongs to the overlapping area of the line 101 and the line 102, the setting of the trackside equipment is not strictly divided in accordance with the dividing point in the jumper area, but a part of the trackside equipment is arranged in the counterpart line. For example, as shown in fig. 1, a transponder 107 is provided on a line connected to the line 101 above the cross-line region dividing point, and the transponder 107 is a trackside device belonging to the line 102. A transponder 108 is provided on a line connected to the line 102 below the cross-line region boundary point, and the transponder 108 is a trackside device belonging to the line 101.
During the indoor simulation test, the trackside simulator of the line 101 and the trackside simulator of the line 102 are information independent of each other. If a train crosses the line 101 and enters the line 102, and before the train tail of the train crosses the demarcation point and enters the line 102 completely, the train-mounted controller only receives the information of the trackside simulator of the line 101. Therefore, before a train crosses a demarcation point to enter the line 102, the line condition of the line 102 cannot be known, so that the train cannot automatically cross the demarcation point to enter the line 102. On the other hand, even if a part of the train body passes through the dividing point and enters the route 102, the trackside equipment cannot update the occupation information of the axle counting section in time because the train does not completely drive into the route 102, and potential safety hazards are brought to other trains running on the route 102.
In order to solve the above problem and ensure the safety of train over-line running, fig. 2 is a schematic flow chart of a method for simulating trackside equipment of an interconnection over-line provided in this embodiment, and referring to fig. 2, the method includes:
201: the line-track side simulator acquires the real-time position of a train running on the line according to the vehicle dynamics model, and judges whether the train runs to a line crossing region crossing from the line to a target line according to the real-time position of the train;
202: if the local trackside simulator judges that the train enters the cross-line area, the local trackside simulator acquires first message information of a target transponder, which is sent by a target trackside simulator; the first message information comprises information whether the target line allows the train to enter at present;
203: the local line-track side simulator sends the first message information to a vehicle-mounted controller of the train, and the vehicle-mounted controller generates control information for controlling the train to run in the line crossing area according to the first message information;
wherein the target transponder is a trackside device belonging to the target line and is disposed in a first line section belonging to the own line in the cross-line region; the local line trackside simulator is used for simulating trackside equipment in the local line; the target trackside simulator is used for simulating trackside equipment in the target line.
The method provided by the embodiment is suitable for indoor test of train operation, and in the process that a train drives into a target line from a local line through a line crossing area, the train operation safety is ensured through information interaction of the local line trackside simulator of the local line and the target trackside simulator of the target line. When a train running on the line enters the cross-line area, the line-track side simulator sends the received information from the target line-track side simulator to the VOBC, so that the vehicle-mounted controller can determine the line condition of the target line before crossing the demarcation point, and the train crosses the demarcation point to enter the target line when the line condition allows the train to enter the target line, thereby ensuring the driving safety.
The vehicle dynamics model receives the traction force and the brake force which are sent by the vehicle controller VOBC and used for controlling the running of the train in real time, simulates the real-time position of the train, and sends the simulated real-time position of the train to the corresponding trackside simulator. The wayside simulator sends the state of corresponding wayside equipment on the line (e.g., the position of a transponder, the state of an indicator light indicating the state of the line ahead, etc.) to the vehicle controller VOBC according to the real-time position of the train, so that the VOBC can adjust the operation of the train in time according to the state of the wayside equipment.
The first message information is information sent by the target trackside simulator to the local trackside simulator, is message information corresponding to the target transponder, the target transponder belongs to trackside equipment of the target line, and the first message information includes information indicating whether the target line currently allows the train to enter (i.e., information reflecting the current line state of the target line, for example, the target line is currently occupied or a signal lamp of the target line is currently red, and the first message information indicates that the train is not allowed to enter). The target transponder is arranged in a transponder belonging to a first line section of the local line in the line crossing region. In this embodiment, before the train crosses the demarcation point, the target trackside simulator sends the first message information to the local trackside simulator, and the local trackside simulator sends the first message information to the VOBC, so that the train can enter the target route after knowing the route condition of the target route in advance, and the safety of the train entering the target route is ensured.
Further, the first message information further includes a location of the target transponder.
Further, the target transponder includes at least one fixed transponder and at least one variable transponder.
The information corresponding to the fixed transponder is the position of the transponder, and the information corresponding to the variable transponder comprises the position of the transponder and the line condition of the line to which the transponder belongs. For example, fig. 3 is a schematic diagram of a track structure for interconnecting and intercommunicating cross-line operations provided in this embodiment, referring to fig. 3, an uplink 301a of this line, a downlink 301b of this line, and a target line 302. The line between 301a and 302 and the line between 301b and 302 are cross-line areas, the dividing point is located at the line intersection position of the dashed straight line and the cross-line area in fig. 3, and the transponder 304 in the dashed circle is a target transponder and is trackside equipment of the target line. The transponder 303 in the dotted circle is a local line transponder, which is a trackside device of the local line. In the method provided by this embodiment, in the process that a train crosses into the target line 302 from the local line (e.g., 301a), before the train head crosses the demarcation point, the target trackside simulator sends the first message information of the target transponder 304 to the local trackside simulator, so that the onboard controller knows the line condition of the target line before the train crosses the demarcation point, and the train driving safety is ensured.
Specifically, the method provided by this embodiment is to cause transponder message information to be mutually repeated between trackside emulators of the crossline. In the design of the interconnection and intercommunication line crossing scheme, two transponders (as shown in fig. 3, a fixed transponder (a transponder with no filling in a dotted line circle) and a variable transponder (a transponder with black filling in a dotted line circle)) on two sides of a demarcation point of two lines are arranged in an opposite line, so that the vehicle-mounted device can obtain information such as an access of a target line through a transponder message when the target line is not crossed, and the information is crossed into the target line.
The trackside simulators of the two lines can associate the transponders on the two lines through the ID information of the transponders, and duplicate the transponder messages, so that the tracksides of the two lines can acquire the corresponding transponder message information, and the trains can smoothly cross the lines.
The embodiment provides a trackside equipment simulation method of interconnection and intercommunication line crossing, wherein information interaction is performed between a local trackside simulator of a line and a target trackside simulator of a target line, in the process that a train crosses the line from the line to the target line, before a train head crosses a boundary point, the target trackside simulator can send first message information of a target transponder to the local trackside simulator, and the local trackside simulator sends the first message information to an onboard controller, so that the onboard controller can determine whether the target line currently allows the train to enter the line information or not through the first message information before crossing the boundary point. Only when the first message information allows the train to drive into the target line, the vehicle-mounted controller controls the train to cross the demarcation point and drive into the target line, and the safety of the train is guaranteed. According to the method, the information interaction among trackside simulators of different lines enables the line condition of the line to be entered to be known in advance in the line crossing process of the train, and the driving safety of the train is guaranteed.
Further, on the basis of the above embodiment, the method further includes:
if the first message information is that the train is allowed to drive into the target line currently, the control information comprises information for controlling the train to drive into the target line completely;
in the process that the train head of the train drives into a second line zone from a first line zone until the train tail of the train drives over a demarcation point, the local line trackside simulator sends a first axle counting zone number and axle counting zone occupation information, matched with the local line, of each axle counting zone in the cross-line zone to the target trackside simulator;
after the target trackside simulator receives the first axle counting section number and the axle counting section occupation information of each axle counting section, according to the mapping relation between the first axle counting section number of each axle counting section and the second axle counting section number matched with the target line, the occupation information of each axle counting section in the cross-line area is synchronized to each axle counting section represented by the second axle counting section number;
wherein the second line section is a section belonging to the target line, which is provided in the cross-line region; the demarcation point is a meeting location of the first line segment and the second line segment.
Since the train only keeps communication with one trackside simulator, the train only keeps communication with the local trackside simulator before the train completely crosses the demarcation point and enters the target route (the VOBC and the vehicle dynamics model also only communicate with the local trackside simulator), so that even if the train partially enters the target route, the target-route trackside simulation cannot know the occupation information of the train on the target-route axle counting section. In the method provided by this embodiment, the line-track-side simulator communicates with the target-track-side simulator, so that before a train completely enters the target route, the target-track-side simulator updates the occupancy information of the axle counting section in the target route in time through information interaction with the line-track-side simulator, thereby avoiding potential safety hazards caused by the delay of updating the occupancy information of the axle counting section in the operation of other trains, for example, affecting the calculation of the movement authorization MA of other trains.
The overline area belongs to the overlapped line of the line and the target line, and each axis counting section of the overline area has a first axis counting section number matched with the line on one hand and a second axis counting section number matched with the target line on the other hand. In the method provided by this embodiment, before the train completely drives into the target route, the route of the cross-route area is represented by a second axle counting section number matched with the target route in the electronic map of the target trackside simulator through interaction between the local trackside simulator and the target trackside simulator, and the axle counting section occupancy information is synchronized to each axle counting section represented by the second axle counting section number.
Specifically, the trackside simulators of the two lines mutually duplicate the occupation information of the axle counting section. When the train is in a line demarcation point by crossing pressure, the line track side simulator can calculate the train occupation condition on the line and search the equipment number (the first axle counting section number) of the axle counting section in the overlapping area in the number comparison table according to the axle counting section ID in the electronic map.
The equipment numbers of the axle counting sections contain line information, and the equipment numbers of the same axle counting section are kept uniform in different line configuration data (the axle counting section in the current line 301a has a uniform axle counting section number, and another uniform axle counting section number is used in the target line 302, so that the axle counting sections in the overlapped lines correspond to different axle counting section numbers in the two lines). The local trackside simulator of the line 301a sends the number (for example, the number of the axle) and the occupation state of the axle counting section equipment in the overlapping area to the target trackside simulator of the target line 302, the target trackside simulator of the target line 302 receives the data and then converts the number of the axle counting section equipment into the ID of the axle counting section of the electronic map according to the data of the line, the ID is searched in the local data axle counting section, and the occupation state of the axle counting sent by the local trackside simulator of the line 301a is synchronized to the target trackside simulator of the target line, so that the CI/ZC of the target line can obtain the timely train occupation condition.
In the process that a train travels from the line to the target line in an overline mode, the line trackside simulator and the target trackside simulator share axle counting occupation information, so that the target trackside simulator can update the axle counting section occupation information in time before the train completely enters the target line, and interlocking or decision making by an object controller which is inconsistent with the line state due to lag update of the axle counting section occupation information is avoided, and the problem of driving safety is brought.
Further, on the basis of the above embodiments, the method further includes:
in the process that the train head of the train drives into a second line section from a first line section until the train tail of the train drives over a boundary point, the line-side simulator judges whether the time interval from the last time when the train real-time position sent by the vehicle dynamic model is received is larger than a preset time interval, if so, the line-side simulator judges that the train tail of the train drives over the boundary point, and the train is deleted from the line;
the preset time interval is greater than or equal to a communication period, and the communication period is a period of communication between the local trackside simulator and the vehicle dynamics model.
For example, the preset time interval is 5 communication periods each of which is 10 ms.
Specifically, when the train crosses the local line, the local line-rail simulator automatically judges that the train crosses the local line according to the chain breakage time of the communication between the vehicle dynamics model and the local line-rail simulator, and automatically deletes the train in the local line. The communication period of the vehicle dynamics model and the trackside simulator is 10ms, if the trackside simulator judges that the train position information of the dynamics model is not received in 5 continuous periods, the trackside simulator considers that the communication between the simulation trackside and the vehicle dynamics model is interrupted, and automatically deletes the train information.
Further, on the basis of the above embodiments, the method further includes:
and in the process that the train head of the train drives into the second line section from the first line section until the train tail of the train drives over the boundary point, the target trackside simulator judges whether the number of times of continuously receiving the train real-time position periodically sent by the vehicle dynamic model is larger than the preset number of times, if so, the train tail of the train is judged to drive over the boundary point, and the train is added into the target line.
For example, the preset number of times is 5 times. And if the target trackside simulator receives the real-time positions of the trains sent by the vehicle dynamics model in 5 continuous periods, the trains are added into the target line of the target trackside simulator, wherein the trains cross the demarcation point and enter the target line.
Specifically, when the train crosses a target line, the vehicle dynamics model automatically starts to send train information to the target trackside simulator, the target trackside simulator considers that the train enters the local line after continuously receiving data of the vehicle dynamics model for 5 periods, and the target trackside simulator recognizes the train through IP information of the dynamics model and starts to communicate with the train to complete the take-over of the train.
The embodiment provides a trackside equipment simulation method for interconnection and intercommunication overlines, a trackside simulator automatically adds and deletes trains, automatic connection of the train overlines is achieved, and normal operation of the trains after the overlines is guaranteed.
Further, on the basis of the above embodiments, the method further includes:
after the first message information of the target transponder changes, the target trackside simulator sends the changed first message information to the local trackside simulator;
and the number of the first and second electrodes,
